Introduction to Gypsum Grinding Technology
In modern drywall manufacturing, achieving consistent gypsum powder fineness is critical for product quality. The grinding process directly impacts setting time, strength development, and surface smoothness of finished boards. This article explores advanced grinding solutions with a focus on high-efficiency mills that meet industrial production demands.
Key Requirements for Drywall-Grade Gypsum Powder
| Parameter |
Standard Range |
Premium Grade |
| Particle Size (D50) |
45-75μm |
30-50μm |
| Moisture Content |
<1% |
<0.5% |
| Whiteness |
≥85% |
≥90% |
Industry Challenges in Gypsum Processing
- Thermal sensitivity: Overheating causes dehydration of CaSO₄·2H₂O
- Fiber contamination: Paper recycling in drywall requires precise impurity removal
- Bulk density control: Critical for transport and board forming
